Discectomy Definition

Discectomy is the surgical removal of part or all of a vertebral disc that has herniated. The disc is removed by first cutting the outer annulus fibrosis and removing the nucleus pulposus to relieve pressure on the nerve root. A dissection is then performed to remove a ligament that runs from front to back in order to access the spinal canal and remove any bone spurs or disc material protruding through the ligament.

There is little chance of a recurrent disc herniation at the segment because most of the disc is removed with this type of surgery.
